  • a Phenotypes of shy mutants are described relative to the corresponding SHY strain.

  • b pom1-14 and pom1-15 seedlings have an altered response to low fluence rates (Figure 5).

  • c Shown are the consensus results for days to flower (DF) and leaf number (LN) at time of flowering. In each column, the phenotype of the SHY plants is taken as normal. Thus, although phyB-1 SHY plants flower earlier than PHYB SHY plants, both are considered “normal” for the purpose of comparing their phenotypes to those of the corresponding shy plants. hyp., hypocotyl.
